What Is an IMEI Number? How to Check It Before Buying a Phone

An IMEI is a number used to identify a mobile device. When buying a new or used phone, comparing the device IMEI with the box and invoice is an important verification step.

How can you view the IMEI?

On many phones, opening the Phone app and dialing *#06# displays the IMEI. Some devices also show it under Settings and About phone.

What should you compare before buying?

Compare the IMEI shown on the phone with the label on the box and the information on the invoice. Dual-SIM phones can have more than one IMEI. If the details do not match, ask the seller for an explanation before completing the purchase.

Check official device status

Some countries provide official services for checking device registration or IMEI status. When using a phone in Bangladesh, follow the latest guidance from the relevant government or regulatory authority.

FAQ

Is an IMEI the same as a phone password?
No. It is a device identifier. Avoid sharing it publicly unless there is a legitimate reason.

Does a matching IMEI prove that a phone is original?
No. IMEI verification alone cannot establish everything. Also check the invoice, warranty, seller, device condition and purchase source.
